Have a 2020 p500 live in colorado and wanted to know if anyone has put the p520 throttle body on the p500. Stock p500 is 36mm and the p520 is 44mm.

@906UP turned his P5 into a P520 motor with parts and labor. He might have some insight on the throttle bodies.

Interesting, when I checked the TB for the 520 it came up with the same part # (size) for the P5, P5.2 and ironically the P700. The injector is also the same between P5 & P5.2 so without increasing the pulse width (injector on time) you'll likely see no measurable difference. If you combine it with a fuel controller you may see an improvement but I'd say it would be negligible at best. Honda rates the 520 @ about 30 hp, the P5 was 28.x hp, there's just not a lot to work with.
